We just ate at both places this past week. I have to say I enjoyed WC more. I thought the food and the atmosphere was better. Ohana's was good, but it was so much meat. I am not a vegetarian by any means, but I also am not a huge meat lover. And for some reason at Ohana's we could not get our side dishes (there are only two, some cheesy potatoes--very good, and some stir fried veggies which I did not care for way too crunchy) even though we told our "cousin" twice that we never got our sides. She just kept coming back over with more meat. My plate consisted of sausage, turkey, and steak, that's it! The sides finally made it out right before desert! I will say the desert was awesome! Yum! But I think they need to give you at least one more side and some bread or something besides meat!
WC was delish, their mashed potatoes were soooo good and corn on the cob, yum, yum. BBQ was good and chicken was great. I would pick WC again. Ohana's, I could skip for a few years.
